Call all colleges you are interested in and let them know the dates, times and location of the showcase. Invite them to see you display your skills. Tell them you will be attending the USBA camp.
Many times coaches and scouts will have seen you play before they know your skill level. They like to see how you react when things do not go your way. If you show a good attitude and composure when you are not having your best day you will leave a good impression in their minds. Anyone can have a great attitude when things are going well, but only true winners realize they are better than what they are displaying.
